Step 14: 9152 + 704 = 9856
Step 15: 9856 + 704 = 10560
Step 16: 10560 + 704 = 11264
Step 17: 11264 + 704 = 11968
Step 18: 11968 + 704 = 12672
Step 19: 12672 + 704 = 13376
Step 20: 13376 + 704 = 14080
Step 21: 14080 + 704 = 14784
Step 22: 14784 + 704 = 15488
Step 23: 15488 + 704 = 16192
Step 24: 16192 + 704 = 16896
Step 25: 16896 + 704 = 17600
Step 26: 17600 + 704 = 18304
Step 27: 18304 + 704 = 19008
Step 28: 19008 + 704 = 19712
Step 29: 19712 + 704 = 20416
Step 30: 20416 + 704 = 21120
Step 31: 21120 + 704 = 21824
Step 32: 21824 + 704 = 22528
Step 33: 22528 + 704 = 23232
Step 34: 23232 + 704 = 23936
Step 35: 23936 + 704 = 24640
Step 36: 24640 + 704 = 25344
Step 37: 25344 + 704 = 26048
Step 38: 26048 + 704 = 26752
Step 39: 26752 + 704 = 27456
Step 40: 27456 + 704 = 28160
